INVENTOR. HARRY A. WHALEY ATTORNEY United States Patent WINDOW MEANSHarry A. Whaley, Wichita, Kans. Application March 9, 1956, Serial No.570,542

Claims. or. 20-55 This invention relates to windows. In a more specificaspect, it relates to'spaced and parallel moving windows, such as doublehung prime windows and storm windows therefore which have portions whichcan be raised or lowered. In a still more specific aspect, thisinvention relates to latch means which can be used to join prime andstorm windows together so that they can be moved together.

Double hung main or prime windows with an upper and a lower sash havelong been known, and storm windows therefore have long been known in theart, the more convenient of which have a sash which can be raised orlowered so that ventilation can be had through the storm window, and thecorresponding raised or lowered prime window sash. Also, means toconnect the prime window sash and storm window sash are known, so thatupon raising or lowering the prime window sash, the storm window sashwill also raise or lower. These prior art means have theirdisadvantages. They are not convenient to use, since they are notdesigned to remain out of the way when not in connecting relation to thewindow members, and they do not provide for compensating for the weightof the storm window member on the prime window when they are connectedtogether. The new latch means of my invention for connecting the primeand storm window sashes for movement together is very convenient to use;it does not interfere with window movement when not in connectingposition; and it readily lends itself to compensating for the weight ofthe storm window member when the windows are in raised position.

I have invented means to join two spaced Window members for movementtogether. The new means of my invention has a retractable membermountable on one of the window members. Resilient means are employedwhich urge the retractable member to extended position. The retractablemember is adapted when extended to engage the other window memberwhereby both window members are moved together when one of them ismoved. In a preferred specific embodiment of my new connecting means,the retractable member is made so that when not in use it lays backagainst the window member on which it is mounted and out of the way. Iprefer to do this by using a spring loaded hinge member which is mountedon one of the windows.

It is an object of this invention to provide new window means.

It is another object of this invention to provide new connecting meansfor joining together spaced and parallel moving prime and storm windowmembers.

It is still another object of this invention to provide new latch meansfor connecting together the lower sash of a double hung prime window anda movable sash of a storm window therefor so that they will raise andlower together when the prime window sash is raised or lowered, suchlatch means being adapted to lay back out of the way when not in use andto compensate for the extra ice 2 weight on the prime window sash causedby operatively connecting the storm window sash thereto.

Other objects and advantages of the new window means of my inventionwill become apparent to those skilled in the art upon reading thisdisclosure.

Drawings accompany and are a part of this disclosure. The drawingsdepict preferred specific embodiments of the new means of my invention,and it is to be understood that such are not to unduly limit the scopeof my invention.

In the drawings, Fig. 1 is an elevation view, in longitudinal crosssection through the portion of the latch means having the retractablemember, showing a preferred specific embodiment of my new latch means inopen extended position.

i Fig. 2 is a side elevation view in cross section showing the latchmeans of Fig. I mounted and attached to window members in operativeposition.

Fig. 3 is a front elevation view of the latch means of Figs. 1 and 2 asmounted on the prime window sash.

Following is a discussion and description of the new window means of myinvention made with reference to the drawings whereon the same referencenumerals are used to indicate the same parts and/or structure. Thediscussion and description is of preferred specific embodiments of thenew window means of my invention, and it is to be understood that suchis not to unduly limit the scope of my invention.

The new latch means of my invention is a hinge member pivotally joinedin approximately the middle portion by hinge pin 5. The end portion 7 ofthe hinge member has holes 9 therethrough which receive screws or bolts11 to mount the latch on the lower sash of a usual double hung windowhaving pane 15 and sill 17.

The other end of the hinge member is a hollow cylindrical housing member19. A plunger latch member 21 is retractably mounted in housing 19. Aspiral spring 23 which acts in torsion is mounted on pin 5 with one endin contact with housing 19 and the other end in contact with mountingend portion 7. This spring 23 acts to urge the hinge member to extendedopen position (the position of Fig. 1), so that when the latch means ismounted on sash member 13 and not in use it will lay back out of the wayagainst sash 13. Spiral spring 25 is mounted in housing 19 with one endin a recess in plunger 21 and the other end backed by pin 5 and spiralspring 23. Spring 25 acts in compression to urge plunger 21 to extendedposition. Housing 19 has a closed slot 27 therein. A latch operator 29attached to plunger 21 in any suitable manner projects out through thisslot, so that by use of the fingers the plunger can be retracted. Theforward edge of closed slot 27 catches operator 29 to retain plunger 21in housing 19. The outer end of plunger 21 has a socket 31 therein toreceive the boss portion 33 on the end of shaft 35. Shaft 35 is suitablyattached to the storm window sash.

The openable storm window sash has a lower rail member 37 and a stormwindow pane 39. As is the usual case, the storm window sash has latchmeans 39 which pivot inwardly to release the storm window sash forraising the window. These latch means are reengaged when the window israised to its desired height. It is preferred to tap these storm windowlatch means 39 and threadedly secure shaft 35 therein, as shown.

End portion 7 of the hinge member is mounted on sash 13 at a point sothat whenplunger 21 is in extended position, and outwardly extendedagainst the force of spring 23, boss 33 will engage socket 31 of plunger21 with the storm window latch 39 in disengaged position. Thus, whensash 13 is raised or lowered, storm window sash 37 will raise or lowertherewith. Latch operator 29 is used to retract plunger 21 sutficientlyso that boss 33 and 3 socket 31 can be engaged, and, of course, operator29 is used to retract plunger 21 to disengage the window latch means,and with such disengagement spring 23 forces housing 19 back out of theway against sash member 13.

With my new latch means it is then possible to open both the prime andstorm windows by merely operating the prime window sash. This is veryadvantageous both in winter and summer for ventilation, eliminating onewindow raising operation. I have found my latch means to be ofparticular value because it conveniently moves out of the way when notin use, and spring 25 compression and/or size can readily be adjusted orvaried to exert force on the windows against the window casings so thatthe windows will remain in desired position. Without a spring 25exerting force on the windows, in many instances the extra weight of thestorm window sash would make it impossible to keep the prime window inraised position with its means for such.

As will be evident to those skilled in the art, various modifications ofthis invention can be made, or followed, in the light of this disclosureand discussion, without departing from the spirit or scope of thedisclosure or from the scope of the claims.
